An engineer is trying to determine how much counterweight she needs to use in order to lift a 22K load (at the position shown). Assume her crane has a 5K chassis but all other parts of the crane, besides the counterweight, have negligible weight. Answer all questions relative to the rotation point. How much torque is caused by the load? How much torque is caused by the chassis? How much counterweight would "barely balance" the crane?
